To all whom, it may concern;

Be it known that we, PETER JAMES CAT- 'TERALL and EDWARD Brncn, bothsubjects of theQueen of Great Britain, residing at Man- 5 chester, inthe'county of Lancaster, England, have invented a new and usefulImprovement in Valves for Regulating the Supply of Water or otherLiquids, (for which we have obtained a Patent in Great Britain, No;5,611, bearing date November 25, 1882, and in Belgium, No. 61,537,bearing date May 30, 1883,) of which the following is a specification.

Our improvement relates to the invention for which we obtained LettersPatent of the United States No.' 253,683, dated February 14,

1882, and is partly or wholly applicable for other purposes and theobjector our invention is to form an improved valve for regulating thesupply of water or other liquid. WVe attain this object by the mechanismillustrated in the accompanying drawings, in which Figure 1 is anelevation showingthe valve applied to apparatus for raising beer orother liquid. Fig. 2 is a sectional elevation upon a larger scale of thevalve. Figs. 3 and 4 are sectional elevations of a modified form of thevalve. Fig. 5 is a sectional elevation of the back-pressure valves. Fig.6 is an elevation, partly in section, of the ball-valve in thewater-supply pipe, and of the treadle for actuating the same. Fig. 7 isa plan of Fig. 6. Fig. 8 is a sectional elevation of an air-vessel forthe prevention of concussion in the water-supply pipe; and'Fig. 9 is adetached view in section, showing our arrangement for connecting thechamber to the water-chest.

Similar letters refer to similar parts'throughout the several views. 7

In Fig. 1, a is the stillage, and b is the barrel containing the beer orother liquid to be raised. To the tap of this barrel isconnected one endof the flexible tube a, the other end 1 of which is connected to abackpressure valve, (1, (shown on an enlarged scale in Fig. 5,)communicating by the pipe with the upper. part of the chamber e. Thischamber is made in halves, and a diaphragm, Z, Fig. 9, of india-rubberor other pliant or flexible material, is fitted in the chamber, theperiphery of the 50 diaphragm being even With the periphery of theflanges of the halves ofthe chamber, which are then bolted together.This diaphragm effectually prevents any liquid admitted to the upperpart of the chamber 0 from mingling with the water or other liquid 5 5admitted to the lower part of the chamber 6. The upper part of thechamber 6 communicates through the back -pressure valve f (shown on anenlarged scale in Fig. 5) and pipe 9 with the deliverytap h. The lowerpart of the chamber 6 is connected to the water-chest j by thetaper-socket t in the manner shown in Fig. 9, and'may be easily removed,if desired. Water is admitted to the water-chest j through the valve(shown on an enlarged scale in Figs. 2, 3, and 4.) and supply-pipe Z,connected to the cistern. To the supply-pipe Zare fitted the air-chamberm (shown in Fig. 8) and ball-valve n, actuated by the spindle n andtreadle 0, as shown in Figs. 6 and 7. Awaste-pipe, p, is connected tothe lower part of the valve is. The bend in the waste-pipe is level withthe top of the chamberaand is for the purpose of keeping the chambercharged with water when the 7 beer in the barrel is run off.

In the valve k, as shown in'Fig. 2, q is the upper and larger diaphragm,and q is the lower diaphragm, both of which are fixed to a tube, q. Theperiphery of each diaphragm is secured between the flanges of the shellor case 70, as shown at 70 and k. A chamber, (1 is fixed to the lowerend of the tube (f. The chamber g contains a ball, g, which rests on andcloses a seating, (1 and thus forms a valve. In the lowest part of theshell 70 is fixed the waste-pipe 19, that may enter the chamber g and beclosed by the ball g as shown in the drawings. To the top of the shellis connected the water-supply pipe Z, provided with the treadle-valve a.From the side of the low est part of the shell projects a pipe, 2',connected to the-water-chest j, to which water is to be supplied. WVhenit is desired to admit water to the water-chest j, the treadle-valve aof the water-supply pipe Z is opened and water admitted to the valve 7c,the pressure of g Water flows through the tube g around v and theair-vessel m.

the ball g" (which then rests on and closes the waste-pipe p) andthrough the side pipe, 0', into the water-chest j. lVhen thetreadle-valve a of the water-supply pipel is closed, a spring,

s, lifts the diaphragms, tube f, and chamber q. The ball (1 is thusraised from the wastepipe 1) and rests on and closes the seating q atthe bottom of the chamber q, and allows the waste water to escapethrough the waste-pipe 1;. As the springs raises the diaphragms, waterpasses through the vent-hole q", (formed in the bottom of the chamberq,) and thus allows the diaphragms to be raised. A hole, k", is made inthe shell 7., and when it is desired to raise the diaphragms, tube q",and chamber q by water, instead of the spring 8, a pipe, 7.5, isattached, which is connected to the main water-supply, the pressure ofwhich is continuous. This pressure of water raises the diaphragms andtube whenever the treadle-valve n is closed, and the supply of waterthrough the pipe Z is shut off from the upper diaphragm,

In the modified form of the valve 7.1, as shown in Figs. 3 and 4, onlyone diaphragm is used, the lower diaphragm being dispensed with. Theshell is made in two instead of three pieces, and the chamber and tube gare formed in one piece. Fig. 3 shows the diaphragm q and tube q raised,the treadle-valve n being closed and the pressure of water in thesupply-pipe if being shut off. The ball q rests in the seating 96' atthe bottom of the chamber q and closes the valve. Fig. 4 shows thediaphragm q and tube q in the position they would occupy when thetreadle-valve n is opened and the pressure of water through thesupply-pipe l is admitted to the valve k. The ball q rests upon andcloses the waste-pipe p, and water flows through the tube q and pipe 1into the water-chest j.

Fig. 5 shows the back-pressure valves (1 and f connected by the pipe 0.Each of these valves (1 and f is formed of a ball resting upon aseating. Pieces of wire (1 and f are fitted to prevent the balls fromclosing the pipes c and g, respectively.

In Figs. 6 and 7, a is the ball-valve, and 0 is the treadle whichactuates the valve-spindle a, secured to a flexible diaphragm, 15*, heldat its periphery between the flanges of the body of the valve. The ballit rests in a conical seating near the foot of the water-supply pipe Z.

In Fig. 8, m is the air-vessel placed between the treadle-valve a andthe water-supply cistern, to prevent concussion in the pipes. m is theindia-rubber air-ball placed within and nearly filling the interior ofthe shell. Zis the pipe which carries the water-supply from the cisterninto and out of the air-vessel m to the treadle-valve a, and thence tothe valve h. To regulate the flow of water in the pipe I, a screw-downtap is placed between the cistern (This tap is not shown in thedrawings.)

Fig. 9 shows the lower part of the chamber a connected by the tapersoeketi to the waterchest j.

The mode of operation of the whole apparatus is as follows: The beer orother liquid flows from the barrel 1) through the tube a, valve 01, andtube a and fills the chamber 0. \Vhen it is wished to draw beer, the taph is opened, and the treadle o is operated so as to raise the ball. inthe valve a and admit water or other liquid through the supply-pipe Z,valve 76, pipe 0', and chest 3' into the lower part of the chamber 0.The pressure of the water forces up the diaphragm in the chamber c,raises the beer through the pipe 5 and delivers it through the tap h.The backpressure valved prevents any beer from being forced back intothe barrel 1). \Vhen sufficient beer has been drawn, the treadle 0 isreleased, and the ball allowed to fall and close the valve or and shutoli the supply of water through the pipe Z. The diaphragms and tube qthen rise in the valve k and allow some of the water to escape from thechamber c and chest 7' through the waste-pipe p, and the beer from thebarrel 1) again fills the ehamberc. The baclepressure valve f preventsany beer from returning from the pipe 9 to the chamber c.

Having stated the nature of our invention and described the manner ofperforming the same, we declare that what we claim, and desire to secureby Letters Patent of the United States, is I 1. The combination of aspring-pressed diaphragm having an inlet, allowing the flow of liquid inthe direction opposite to the press ure of said spring, with a tubeextending through said diaphragm and movable therewith, two outletsarranged below said tube, and a valve which closes one of said outletswhen the liquid flows as aforesaid, but leaves it open when the liquidceases to flow in that direction, substantially as set forth.

2. In combination with the beer-vessel, pipes, backflow-valves, anddiaphragm-chamher 0, arranged substantially as described, devices forletting 011 or cutting off the sup ply of water at any time, and a valveprovided with a spring pressed diaphragm, a tube extending through saiddiaphragm and movable therewith, two outlets-one extending to thediaphragm-chamber c, the other allowing escape of water-and a ball whichautomatically closes the latter when the flow of water is let on toforce out the beer, substan-v tially as described.

The foregoing specification of our improvement in valves for regulatingthe supply of water or other liquid signed by us this 30th day ofOctober, 1883.
